- Key message
- We isolated 24 sequences which have putative functions in distinct cellular processes, such as transcription regulation (OsWRKY80), stress response (OsGAP1, DEAD-BOX RNA helicase), proteolysis (oryzain-alpha, rhomboid protein), photosynthesis (chlorophyll a/b binding protein), sugar metabolism (beta glucosidase) and electron transport (NADH ubiquinone oxireductase)
- The finding that OsYchF1 and OsGAP1 are involved in plant defense response might shed light on the functional roles of YchF homologues in plants
- G-proteins (guanine nucleotide-binding proteins that usually exhibit GTPase activities) and related signal transduction processes play important roles in mediating plant defense responses; here, a rice (Oryza sativa) cDNA clone, OsGAP1, encoding a GTPase-activating protein (GAP) that also contains a protein kinase C conserved region 2 (C2) domain is reported
- On the other hand, the ability to alleviate salt stress by OsGAP1 is dependent only on its ability to bind OsYchF1 and is independent of its phospholipid-binding activity

- OsGAP1, OsRab11, OsGAP1 functions as a positive regulator of OsRab11-mediated TGN to PM or vacuole trafficking, Thus, the OsGAP1 mutants may inhibit TGN to PM or central vacuole trafficking because they induce the sequestration of endogenous Rab11
- OsGAP1, OsRab11, OsGAP1 functions as a positive regulator of OsRab11-mediated TGN to PM or vacuole trafficking, We propose that OsGAP1 facilitates vesicular trafficking from the TGN to the PM or central vacuole by both stimulating the GTPase activity of OsRab11 and increasing the recycling of inactive OsRab11
